So a couple of my niches on youtube have been doing really well. I did burn some cash and got one video taken down but it helped me learn a couple things which I then implemented into the next couple uploads. So now i'm getting ready to scale up but first I want to setup a multi niche website under one, aged domain. I don't want to completely rely on youtube traffic, so working with SEO as I upload more niches is going to be key.

Now for my actual question; How should I go about making a multi-niche website? Are there any threads here on CPAelites that would be helpful? Also where can I purchase an aged domain that wont break the bank but is also sorta niche related?
